How to start several sessions from a single project file with tmuxinator

I was trying to run several sessions from a generic project file with tmuxinator, without having to use an alias with the -n option.

I realized that the project files support ERB , which is nifty. That’s how I came up with the idea to generate a new session name every time with ERB :

project_name: generic_<%= Time.now.strftime("%d_%m_%Y__%H_%M") %>
windows:
    - dev_window:
          layout: even-horizontal
          panes:
            - ls
            - vim

This can looks pretty ‘hacky’, but it’s just for the sake of having every info about the project in same file.

You could also use

<%= (0...8).map { (65 + rand(26)).chr }.join %>

if you want a totally random string.

Tested with tmuxinator 0.8.1
